FORMING PREFORMS AND PARTS THEREFROM |
摘要 |
A method for forming a component includes forming a workpiece into a hollow preform cylinder concentric with an axis and including an inner surface that extends along the axis, placing within the preform cylinder a mandrel having an outer surface, flow-forming the inner surface and the outer surface of the preform cylinder such that the inner surface of the cylinder conforms to at least a portion of the outer surface of the mandrel, and cutting the flow formed cylinder transversely with respect to the axis into segments, each segment having an axial length.
